"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!"

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

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.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.
