"Jeff and his team did and excellent job with the installation of two Daikin HVAC units. I had many questions about the units and install and they were quick and thorough in responding. The price and warranty were competitive with high end brands. The crew was courteous and professional during the two day install. They were the only company that included replacement of the coolant lines, rather than just flushing the old ones. So far the Daikin variable speed AC units are exceptionally quiet and the house is very comfortable. Would recommend Ace Home Services and Unique Comfort without reservation."

"We have used Gen3 on a couple of different jobs. They installed a new circuit breaker, two ceiling fans, redid all of our outlets and installed a common wire for our HVAC. Each time we reach out to them, they respond promptly and send out competent, professional, and courteous people. They make sure they wear booties and cover up furniture when necessary. I have recommended Gen3 to my friends and family as well. Cannot recommend them enough!"

"I did not expect someone to answer my call on New Years Eve but when I was greeted with a happy how can we help you. I knew if was a good start. I have used Homeadvisor before and had Excellent Service. I must say FAHRENHEIT INC went above and Beyond. They did not hesitate to come out and fix the issue immediately. The tech was extremely knowledgeable and efficient. I would Highly Recommend Fahrenheit for your HVAC Needs. I will use no other!"

"Joe came and was very professional.  We enjoyed talking to him about our needs and he made several recommendations about how to address our concerns.  He provided several professional written estimates by email within a few days.  In the end we decided to use the idea of a different company but we were impressed with Joe.  We would consider using DiBiase in the future for any of our heating or cooling needs.

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"I would give MORE stars if I could. Service was excellent. Greg arrived at the appointment time, was clear about what he would do and how he would do it. He was very clean in his work. He removed all duct covers, then began the cleaning. I had some issues with the antibacterial disinfectant (allergies) he would be using. He advised I could research it and let him know. He even allowed me to smell the disinfectant. We did use it and the smell was very mild and dissipated in about a half hour. After cleaning the duct work, he returned all the duct cover and cleaned up his work area. He worked by himself and had the job done in under 3 hours. And the price was fantastic, coming in at over $150.00 and $300.00 less than 2 other bids. If you're looking for duct cleaning for your HVAC system or dryer (he did that, too!), The Duct Pros are where you want to go! Thank you Duct Pros!"

"Marcel is the man. Came through on a Saturday to look at what would be needed for my install, and got the job done by Monday evening. Also took the time to keep the entire job site spotless and walk you through the whole process. Cares about doing the work right and is an all around professional. Will definitely go with Strive for all my HVAC needs in the future."

Heating and Air Conditioning FAQs, answered by experts

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.
