"We found CLIMATE MECHANICS from their stellar reviews while searching for a knowledgeable and competent HVAC company. For years, we were dealing with a condensation problem with our LG mini split air conditioner, and no one could find the source of the problem. We can honestly say that we've never experienced a company like CLIMATE MECHANICS so committed to making things right. Nate, the awesome climate mechanic that came to our home, and Robert, the owner of the company, could understandably have walked away because they did not install the system and were not responsible for the problem. Nate worked for hours trying to locate the problem. In the end, after so many years of leaking, CLIMATE MECHANICS went above and beyond and resolved our ongoing problem. Toni, their wonderful contact person, told us repeatedly that Robert just wanted us to be happy in the end. And we are. Totally. Thank you Robert, Nate and Toni."

"We use Laury for repair and maintenance of our heating and cooling units for our rental properties and each time we need something done, the staff at Laury never cease to provide quality service. The technicians are always knowledgeable, thorough, courteous and pleasant. We recently had an HVAC system installed in one of our units and the home is rather large and is over 100 years old and there was not a whole lot of empty space to work with. The guys at Laury were able to install the system and all of the duct work and components involved neatly with the age and make-up of the home in-mind. They were pleasant throughout the entire installation which took almost a week. They were always on time and always communicated the process with us. Laury is a trusted business with many years of experience behind them. Prices are also extremely reasonable given the cost of services right now. Warren you are the man!"

"Both Brian and Brian arrived at my home on time. They started with the air duct cleaning, and since my house has centralized heating and air conditioning, they started with the HVAC unit. In addition to their punctuality, I was impressed by the quality and speed of their work. For instance, even though the estimated time frame for the work was 5 hours, the actual length to do this work turned out to be less than 3 hours. In addition, they were very knowledgeable, thorough, helpful, and professional. I would highly consider hiring them for this type of work again."

"Where do I start?! Let me just say, from beginning to end, it was 100% professional. These guys came on time, they did their job, they cleaned up, very professional, straightforward, hard-working, and much much more! They installed a water heater with no issues. The old water heater was picked up. I recommend them to do any HVAC for you! I will be calling them to install an air conditioner unit in the Spring. They were so kind, quiet and just did their job. I am so happy that I chose them amongst other HVAC quotes. Call them today! You will not be disappointed! Thank you guys for a job well done!! Now I can sleep at night, knowing my water heater will be working correctly!"

"We are very pleased with the work performed by Pure Aire. We had all of our HVAC ducts and dryer vents cleaned and the improvement in the air and clothes dryer performance was immediately evident. The appointment was made very easily, the crew arrived promptly as scheduled and professionally performed the work while informing us of their progress and any issues. We plan on using them again and highly recommend them based on our positive experience."

Heating and Air Conditioning questions, answered by experts

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
