"We noticed a foul smell coming from one of the vents in our HVAC system. We turned the system off and called AC Dave. Dave sent Justin and James to troubleshoot the problem. They quickly found a tear in one of our ducts--and the remains of a dead rodent. They cut open the duct, cleaned it and resealed it. We had heat again, about an hour after they arrived. Very fast and competent service."

"Worked with Tim - was looking for new HVAC system. He was honest and provided the best price for what you got (literally thousands of dollars cheaper from other options I was finding). Was very communicative and easy to work with. He made sure to educate you on the ins-and-outs of HVAC systems, and did not try to upsell you like other companies might do. He and Efficiency Air definitely got me as a new continued client."

"I highly recommend Belle Air Services! From the first moment I called to get a quote, to the moment they finished the job, I could not have asked for better customer service, top notch work, and competitive pricing. They communicated with me all throughout the process, made sure I understood everything that would be done, were on time, protected my home and were clean. They even worked very well with my HOA (who is very tough!). And to top it off, they didn't try to up-sell me as other HVAC contractors have in the past. So pleased that I have found this HVAC company!!"

"Haroon was amazing, showed up in less than an hour on a Saturday, immediately found the issue in my HVAC system and explained it, had the part needed and gave me some pointers for the future. He was quick, professional, and very reasonably priced. Will definitely hire him again if the need arises."

"Joel responded right away and got to our property shortly after. He clearly explained what was going on with our HVAC heater, along with pictures of the problem, and went and got parts and completed the job all in time for us to have heat into during the cold night. Great job!"

Heating and Air Conditioning questions, answered by experts

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

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.
