"We hired DoneRite HVAC to replace our 17 year old HVAC system and we couldn't be happier. This is such a friendly family run business. Garrett from DoneRite promptly came out to check our unit, answered all of our questions, and the very next day we received the quote for the work to be done along with 4 possible HVAC systems in different price ranges to consider. Garrett was very concerned about our comfort while we waited for the new unit to be shipped. The old unit was leaking freon and the temperature in the house was staying around 87 degrees. He made an extra trip out to add some freon to keep us comfortable until the new system arrived, and called several times during this period to make sure we were okay. On installation day, Garrett and his crew did a very thorough job. It was obvious that they wanted to make certain that everything was working perfectly before they left. All of the employees that we interacted with were very nice, and concerned about us. They are an honest, meticulous, knowledgeable, professional business, and we felt that their prices were very reasonable. We will not hesitate to call them in the future when we need A/C or heating work done."

"Mark and his crew did an outstanding job. Mark took before and after photos of the HVAC system to show the difference. Not only does Mark conduct himself in a very professional manner, his crew is also very respectful and professional as well. From start to finish this work was a definite value for the money. I will be using Patriot anytime the need arises."

Heating and Air Conditioning questions, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.
