Do I Need My Heater Repaired?

When your heater fails to start or blows only cold air, it's a clear sign that it needs prompt repair. Yet, your heating system might signal problems before a significant breakdown occurs. Watch for unusual noises, strange odors, cold areas in your home, the need for frequent thermostat adjustments, or a sudden spike in your heating costs. These are all indicators that you should reach out to Oliver for a professional HVAC inspection.

Types Of Heaters We Service

As a top heating company in Talleyville, Oliver has a team of expert HVAC technicians who are highly skilled and experienced with all the heating technologies in the area. Whether you have a furnace, heat pump, boiler, or a system powered by electricity, natural gas, propane, or oil, we’ve got you covered.

Furnace Repair

Furnaces are the most popular heating system choice in Talleyville and can be powered with natural gas, propane, oil, and even electricity. These forced-air systems deliver warmth via ductwork and vents and require seasonal maintenance due to the regular wear and tear and dust accumulation that occurs.

Heat Pump Repair

As technology advances, heat pumps are becoming a more popular choice due to their high efficiency and dual functionality. They not only heat your home in winter but also provide cooling during the summer months. Additionally, heat pumps can be combined with furnaces in a hybrid system to more effectively manage even the coldest temperatures.

Boiler Repair

Boilers are a type of hydronic heating system that uses piping to distribute hot water or steam. This heated water or steam is sent to radiators or similar fixtures, which then release warmth into your living space. Like furnaces and heat pumps, boilers need regular seasonal maintenance to ensure they operate efficiently and effectively.

Have Peace Of Mind With Heater Maintenance

The best way to avoid needing a heater repair this winter is to schedule seasonal maintenance, and Oliver offers maintenance plans that make getting that service more convenient and affordable. We provide maintenance for all types of heating systems no matter their age, and that service includes a multipoint inspection, comprehensive cleaning, lubrication, tightening, and so forth. In addition, should your furnace ever need a repair, plan membership will provide you with a discount on that service.

Lynne M.

Oliver has always provided us with great service. I have contracted with them for a number of years and they come out twice a year to clean and service my furnace/ac units, which they installed about 4 years ago. The technician who was here recently (spring 2026) was Emily Keiderling and she was wonderful (loved seeing a female in this male dominated field!). In addition to prepping the ac unit for summer, she also addressed an issue with the thermostat. She had a young man with her (he has been here before and is also wonderful but I do not recall his name, unfortunately, to mention him personally here). They were clean (wore shoe covers), skilled and professional. They even took the time to neatly coil the garden hose after they were done using it to clean the ac unit. Very thoughtful! I highly recommend Oliver.

I was very impressed with the service technician, Aiden McHugh, who did the annual maintenance on our AC unit. He did a very thorough examination and made sure that everything is working properly.

New review 04/24/2026:
The old system finally gave out after years of reliable service, thanks to Oliver keeping it running as long as it did. I had Oliver install a new HVAC system, and Ron and Jeffery handled the installation. They did an outstanding job—everything looks great, and no detail was overlooked, very professional job. The system is performing better than any I’ve had in this house before. They took their time, ensured everything was working properly before leaving, and even walked me through how to use the new thermostat. Thank You.

Older Post around nine years ago;
Thank God I switched over to Oliver Heating. Your technician Mike is very knowledgeable and professional and courteous. He picked up on a problem the first time he was here that the other company had missed for years.He always seems to go that extra mile for his customers. And Debra is always so helpful on the phone.You have a great team there Oliver. Thanks.

Marge H.

When we make an appointment for our usual service for our heat pump maintenance, it was done professionally and in a timely manner. When the technician, Tan Mai came (on time) he was friendly, professional and more importantly to us as senior citizens very knowledgable, and he took the time to explain everything to us in a way that we could understand. He also gave us pointers which was very appreciated, especially since our heater/heat pump is 13 yrs old, over the 10 year warranty period. We opted to replace our capacitor (voltage stabilizer) and it was done quickly and we’ll now have peace of mind! We have always had good service on prior occasions but Tan was exceptional! Thank you Olivers and Tan for your continued excellent service!

Perry Robinson was professional and honest during our maintenance service. Would highly recommend.

Ila P.

This was my first time using Oliver HVAC and I was very impressed. Alex Little, who is a project manager, came to check on my water heater. He thoroughly examined the problem and did the site survey. He explained to me all the details about my old water heater and how badly it was installed with a plastic and metal exhaust pipe and it was against the code requirements. He is very professional and knowledgeable. He took the time to explain to me the process of replacing the new unit with new pvc venting for exhaust. Alex and his team, Tashaun and Anthony did a great job. Tashaun and Anthony cleaned the area very nicely after installing the unit. They were very polite and professional.
Thank you for your exceptional service. I highly recommend Oliver HVAC.

James J.

Perry Robinson came and did our inspection today
He was very professional and informative

Dave P.

I wanted to share about the professionalism and friendliness of Anthony Zuppo, an Oliver HVAC technician. He was very thorough in his work to tune up my AC unit in prep for the summer months. I was impressed with his honesty and “no pressure” suggestion to upgrade my compressor and A-coil since they are approaching end of life and that some of the circuit boards were looking pretty bad from normal wear and tear. I would highly recommend Anthony and Oliver to anyone looking for a quality maintenance structure in maintaining your HVAC equipment.

Nick j L.

Walt O’Brien was super professional and friendly when he came and serviced my HVAC system. Runs like a charm!

Nancy K.

Oliver installed window well covers for us. They look terrific and will certainly do the job. The technician, Dale, did a wonderful job. Oliver has established a high standard in all the work they have done in my home over the years. Another job completed with the same high quality.

Howard M.

Judah was knowledgeable and throughly excellent.

deborah S.

Joe E from Oliver Duct Cleaning - fabulous service, very thorough and good at explaining how things work

David B.

The installation team consisted of Tommy, Clint and a junior technician. Tommy arrived early and we discussed access, set-up, and technical approach. Tommy prepared the area so that when Clint and the equipment arrived, the installation was quickly underway. After the thermostat was placed, Clint provided a clear tutorial of its operation. Clint and I then inspected the installation of the air conditioner and the gas furnace. All of my questions concerning purpose, operation, and maintenance were answered. I appreciate the tips and insight that Tommy and Clint provided. Clean-up was meticulous. Altogether a very satisfying experience for a conscientious homeowner.
