"Very prompt to respond to my call. Service person very pleasant and knowledgeable. Reviewed in detail what he thought problem was. Offered to have me sign up for regular service visits twice a year which made cost of this visit nothing so I agreed. Said they would order part he thought I needed and have it available if required which I appreciated. He wrote some descriptions of the HVAC system in his notes which described ducts as in " poor condition " but didn't mention that to me. I thought he should have. Will use again."

"We had a totally broken HVAC system in our 30 year old house. They came in and fixed it in two days. The guys were very friendly and answered our questions. Our original salesperson was knowledgeable and respectful considering the state of our equipment at that time. Now we have heat for the rest of the Winter and AC for next year. Thank you!"

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"Rick and his team were awesome. They were very thorough, put everything they moved in my garage back and Rick made sure to have me check both the heater and AC once installation was complete. He also installed my smart thermostat for me. I would highly recommend Rick and his team."

"I hired Volkman Heating and Air to install a heat pump system for three rooms. That was all I wanted. But, when they were finished, I decided to have them do the rest of the house as well. Anyone can promise you great, professional service. Itâ s rare that they actually deliver everything they promise without compromise. Thanks! Iâ m now ready for the heat of summer to begin."

"Tony was knowledgeable and explained the step by step service to be performed and why it was important to a heating system for efficiency and general maintenance. I thought the price was not inexpensive. However, I chose Ramirex Duct Cleaning due to Tony's presentation. Tony and his 2 assistants were neat, efficient and careful. My 24 year old furnace blade system and 10 vents were cleaned as well as the dryer and vent system within 3 years. Tony took before and after pictures of each phase of the operation which was impressive."

Heating and Air Conditioning FAQs, answered by experts

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years
