Our Most Common FAQs

We Can Answer That!

We know the world of HVAC and plumbing can be a little overwhelming for those who aren’t familiar with it. That’s why at Oliver, we’re happy to answer any questions (short or long) you may have about your home or business’s operations. Here are some of our most common FAQs, answered:

What’s the best air conditioner size for my home?

If the size of your home has changed through an addition or other renovations, or you have made enhancements that affect air flow (such as window or door replacements or changes to your insulation), it may be time to have a professional perform a new Heat Load Calculation on your home to assess the proper size air conditioner. If you are installing one for the first time, a Heat Load Calculation is recommended.

How can I even out the heating and cooling of my home?

You can partially close the registers in the room(s) that are too hot or cold in order to force more airflow into other rooms of your home. (It’s never a good idea, however, to close the registers completely.) Another possible solution is to invest in a furnace equipped with a variable speed blower motor. These furnaces are designed to overcome airflow problems and keep the airflow steady throughout the entire house.

How does an air conditioning system actually work?

An air conditioning system consists of 2 parts: an outdoor unit (where liquid refrigerant is contained) and an indoor coil (where the refrigerant is pumped into). As the air moves across the air conditioning coil, the refrigerant removes the heat and moisture from the air by condensing it on the cold surface of the coil. Thus, an air conditioner not only cools, but also dehumidifies the air.

When should I call a plumber?

This depends on your own skill level and experience in making repairs. If the repair could cause water damage if not performed properly, you may want to call a plumber. It’s also a good idea to call one if you have a problem that needs to be addressed immediately (such as a major leak).

How do plumbers find leaks?

Finding leaks is mainly a visual process: a plumber will inspect all of your pipes for leaks and may use a dye test kit to identify a leak in a toilet. We offer FREE dye test kits as a courtesy to our customers, just give us a call or use the Request Estimate form to let us know you would like one.

If I go away for an extended period of time, what temperature should I set my thermostat to?

We recommend 55 degrees. It’s low enough to save you energy and money but a good temperature to protect your pipes and other vital parts of your structure.

How often do my filters need to be changed?

You should change your standard furnace filter every 6-8 weeks. Use your own judgment as to when to change it, but don’t let the filter get clogged, as this can cut down on the efficiency and/or cause damage to the unit.

What can reduce the air quality in my home?

A wide range of particulate matter can be in your home’s air including dust, pollen, animal hair and dander, dust mites, mold spores, cooking grease, smoke, bacteria, viruses and other respiratory diseases. These types of contaminants won’t affect all people, but they can affect some pretty seriously.

Why should I invest in a maintenance plan?

Our maintenance plans provide peace of mind. When your HVAC system is running at its best, you’ll worry less about major damages or a shortened lifespan. You’ll also get priority service, savings on repairs, and no residential overtime charges.

Which HVAC maintenance plan is right for me?

It depends on the level of protection you’re comfortable with. Most of our customers choose our Gold maintenance plan because there are no charges for covered repairs. If you have new equipment, you may find that the Silver maintenance plan provides you with sufficient coverage.

Jim & Brent came out today to take care of both items, and they could not have been more friendly or accommodating!

They were both very professional, and I’d absolutely recommend Oliver to anyone!”

Why Oliver Is Different Than Other Contractors

HVAC service company

At Oliver Heating & Cooling, we take pride in being different than other contractors. For more than 40 years, we’ve been one of the most trusted names in the area and we plan on keeping it that way. Find out what our HVAC service company has to offer.

A Unique History

At Oliver, our company didn’t start like most others. In fact, we have a very unique story behind our founding, and it has to do with a church prayer meeting. When Joe Oliver was downsized from Boeing Helicopter Division toward the end of the Vietnam War, he was left unemployed and needed to find a way to support his wife and six sons.

After he shared his concerns with his church prayer group, one member suggested he open an HVAC business. Even though Joe had no experience in HVAC, he decided to follow the suggestion and opened Oliver Heating & Cooling in 1971. Joe was dedicated to the industry and attended night classes and worked 14-hour days. The hard work paid off and years later, Oliver is the successful business that it is today.

Extensive Training

Our HVAC business knows how important training is, and that’s why each and every one of our contractors goes through an extensive program to earn their NATE Certification (the highest certification in the industry). This ensures that their workmanship is both professional and trustworthy. In addition, our employees must complete our Character-First Program that teaches them how to build a culture of integrity, resolve conflict, encourage employee morale, and more.

Our Hires

At Oliver, we don’t just hire anyone with a background in HVAC or plumbing. We carefully select each of our employees based on personality, experience, and background. We perform thorough background checks and drug screenings on every applicant and make sure they have the right qualities to fit our high standards. You know when you call Oliver, you’ll get friendly, reliable service.

The Latest Equipment

As technology gets more innovative, so does the need for the latest equipment. Our company trucks and vans are always fully stocked with the tools needed to get nearly any job done. Whether it’s a simple repair or an entire replacement, we’re always ready to help.

Customer Satisfaction

Since we opened our doors in 1971, we’ve been satisfying homeowners and business professionals throughout the Delaware Valley and beyond. Our customers, both old and new, count on us for a variety of services and we’re happy to help with the most professional and affordable options. Our expertise and friendly attitudes are what keep people coming back of years on end.

At Oliver, our employees are an incredibly important aspect of our business, so we make sure to treat them right. We offer 100% medical coverage, a 401k program, workman’s compensation insurance, life insurance, and more. After all, happy employees mean a better business.

We’d love to show you exactly what makes us different from other contractors, so whether you have a small problem or a big issue, give us a call today. We’d be happy to help.

What to Look for in an HVAC Contractor

At Oliver, we know trying to decide on an HVAC contractor can be tough – you want the best equipment, but don’t want to be overcharged. You also want to talk to friendly, knowledgeable technicians who have experience and can get the job done right. We’ve put together a little checklist to help you know what to look for in a good contractor:


When someone discovers an HVAC contractor they can trust, they often stick with them, so ask your friends or family for recommendations. If they’ve found a great company, they won’t hesitate to let you know.


A good HVAC contractor should abide by regulations, so look into your state and local codes and regulations to make sure the one you’re considering does. Then, ask questions – ask to see their license or ask for the license number. Also ask about their business insurance and workman’s compensation insurance, both of which they should have for safety reasons.

A Written Estimate

HVAC contractors should have no problem giving you an estimate in writing for your equipment and their services. If they don’t (say they only offer you one over the phone), take it as a little red flag and talk to another company. Also, getting estimates in writing makes it easier to compare them and choose the best one.


A good HVAC contractor should be able to assess your situation, review all of your options, then help you decide on the best solution for your home and your financial status. If you have any questions, don’t hesitate to ask – a knowledgeable technician should be able to answer.

NATE Certifications

A trained and qualifiedHVAC technician should have completed a program offered by the North American Technician Excellence Inc. and have gotten a NATE Certification. Make sure the contractor you want to hire employs technicians with these certifications.

Customer Service

When you talk to an HVAC contractor, pay attention to the way you’re treated. If they are friendly and you’re treated well, it’s a good sign that that’s how you’ll be treated if there’s ever a problem. On the other hand, if you’re not satisfied with their customer service, find someone else so you don’t run into problems later.

Whether you’re interested in a new HVAC system, need an electrical repair, have a plumbing issues, or want to have your insulation assessed, our HVAC and plumbing company can help. Give us a call today for more information and to set up an appointment.

We’re Here for Your Furnace and Plumbing Needs

emergency plumbing serviceWith a blizzard on the way, the heating service experts at Oliver Heating & Cooling just want to remind our customers that we’re here in case you need us. We know that snowstorms can bring unpredictable situations, like power outages or burst pipes, and we encourage you to call us at 1-877-757-1141 if you’re in need of heating or plumbing services.

If your heater malfunctions or stops working, our heating experts can come out and take a look at it. After we assess the problem, we’ll work quickly to get your heater back up and running so that you and your family can stay warm.

On the other hand, if you have a plumbing problem, we can send a plumbing specialist to your home. Whether it’s a clog, an air pocket, a burst pipe, or another situation, we’ll get it fixed and get your plumbing back to normal. We service the areas of Chester, Delaware, Montgomery, and Philadelphia Counties in Pennsylvania; New Castle County in Delaware; and Atlantic, Cape May, Cumberland, Gloucester, and Salem Counties in New Jersey.

On behalf of all of us here at Oliver, we urge you to be prepared for the upcoming blizzard and for the rest of the winter.

Why We Offer Flat-Rate Pricing


Same image re-taken and re-framed. Now we can see their expressions, and get a better feel for the scene.

At Oliver Heating & Cooling, we want to make our HVAC, plumbing, and electrical services as easy and hassle-free as possible for our customers. That’s why we offer flat-rate pricing.

Flat-rate pricing means that you know exactly what the cost of a repair will be before the technician begins the job. You won’t have to worry about variables like the cost of parts for your brand of equipment or the amount of time it will take to complete the repair.

If we were to only offer hourly pricing, we can bet that many customers would be worried about the time it takes one of our HVAC service experts to finish the job. With flat-rate pricing, however, you’ll pay the same price no matter whether it’s a textbook fix or if our HVAC repair service expert runs into a challenge and needs some extra time to make the repair.

The same goes for a part that you may need replaced. For example: If two customers with different brand equipment both need a blower motor replaced in their gas furnace, they’ll pay the same price regardless of the fluctuation in the cost of the part for each specific furnace.

We know that many of our customers prefer knowing the cost of a product or service before they buy it, so when we assess your situation (whether it be an HVAC or a plumbing situation), we’ll give you a fair price quote that’s easy for you to understand. You won’t have to worry about any hidden costs.

Give us a call at 1-877-757-1141 or request an estimate for your HVAC or plumbing repair or replacement. We’ll get the job done as quickly as possible, and you can sit back and relax knowing that what you’re quoted is your bottom line.

Where We Came From: The Story Of The Dove

white dove in the skyAlthough the Oliver logo has evolved several times since the doors of Oliver Heating & Cooling opened in February 1971, one central image has remained – a white dove, symbolizing the company’s roots in founder Joe Oliver’s deep faith. From its beginning at a church prayer meeting, the Oliver company has become a testament to hard work, perseverance, and dedication.

Joe Oliver’s story begins in a way that is all too familiar to many Americans today. As the Vietnam War was winding down, Joe was 1 of 10,000 employees downsized from Boeing Helicopter Division where he worked as an engineer. He held a Master’s Degree in Engineering from Yale University, had served as an engineer for the Sikorsky Division of the United Technologies Corporation and as Operations Research Group Leader for Boeing, but was facing unemployment. With his wife, Beverly, and six young sons counting on him for support, Joe struggled with how to provide for his family.

Joe shared his dilemma one day with his church prayer group. After prayer, one of the

group members suggested that he start a heating and air conditioning business. This suggestion came as a surprise to everyone, including Joe, who had no knowledge of or experience in the HVAC industry. He decided to follow his experience in trusting God, and along with Beverly opened the doors of Oliver Heating & Cooling in February of 1971.

Through perseverance, attending night classes, and working 14-hour days, the business grew and flourished. When Joe was ready to hire his first employee, a man named Adam stepped up to the plate. This coincidence, coupled with Joe’s strong beliefs, encouraged him that he had chosen the right path.

Over the years, the company has grown from one man’s leap of faith to a company of more than 200 employees offering heating, cooling, plumbing, electrical, indoor air quality, and home remodeling services to residents of Pennsylvania, Delaware, and New Jersey. Three of Joe’s sons also work for the company: David, Residential Sales; Bill, the Foreman of the Sheet Metal Shop; and John, a teacher who works as a Warehouse Assistant during the summers.

The success that Oliver has experienced since 1971 is deeply rooted in Joe’s strong faith, his wisdom, and his unwavering sense of integrity and honesty. To remain strongly rooted in Higher Principles, the dove serves as a significant and symbolic point of reference in the company logo.

The unique history of the company, and its founder’s guiding principles set Oliver apart from its competition. As the company approaches 50 years of service to the community, its commitment to providing a superior customer service experience, motivated by a passion for God and a compassion for people, remains strong. The Oliver mission is:

“To build a trusting, long-term relationship with our associates and serve our clients’ indoor comfort needs by honoring God in all we do and treating others as we want to be treated.”
